Epigenetics

Mr. Anderson discusses epigenetics, exploring the interplay between nature and nurture. He explains how identical twins can have different traits due to environmental factors, using the agouti mice study as an example. The video covers the concept of gene expression and differentiation in stem cells, and introduces mechanisms like DNA methylation and histone acetylation. It also highlights the role of microRNA and the importance of the epigenome in health, emphasizing that changes in lifestyle can affect gene expression and be passed to future generations.
